This is a great scan tool, a large one, with great capabilities! On a serious note, one of the reasons we choses this scan tool was the VCI. The better scan tools today use wireless VCI's (Vehicle communication interfaces), but this one takes it one step farther using WIFI to communicate between the VCI and the scanner instead of bluetooth. WIFI allows for communication over greater distances, at least 60 feet. Additionally WIFI has the ability to transfer data at a much higher rate, and is less prone to interference when compared to bluetooth. The VCI has it's own touch screen and can also serve as a J2534 device to facilitate programming / reprogramming of vehicle modules. On top of all that, the VCI can also connect to the internet to allow a technical specialist at a remote location to perform diagnostics or reprogramming on the vehicle. This scan tool is the flagship of Launch's lineup and is extremely powerful, you will not regret buying it!

Not a good product

Very easy to use and did exactly as expected. I had a service light on which I was sure just due to the fact that I did my own oil change. I was very easily able to clear that code and check for any other diagnostic issues. Took less than 5 minutes. Well worth the cost!!

My second time using the tool I was unaware the vehicle had several grounding issues in the electrics, burnt up the end of the cable that plugs into the obd port and was pleasantly surprised that the end of the cable is serviced separately from the cable or vci! What could have been a thousand dollars to replace on some scan tools due to damage to the vci or hardware was a $20 fix and two thumb screws! Having gotten to use it without issue since then the module mapping is incredibly useful. The scanner is quick to connect and pull codes or live data up, shorter wait times mean higher productivity which is a great thing in the shop. It comes very well equipped hardware wise, and has plenty of features other scanners don't have like being compatible with launch's additional oscilloscope kit. It is similar in size to most equivalent scanners from other companies but is heavy in the hand and well built.

Works great on My Audi TT, scans all systems and shows a couple weird codes standard scanners couldn't pick up.Does NOT show any emissions information which is why I bought it in the first place.

not happy, to me this scan tool have no difference than regular 500$ scan toolif I'm replacing ECU or DME because it's go bad and this tool can't do this job so what is the point to write in description ECU reprograming, wase of money

Takes some time to get set up, but goes smoothly if you follow the instructions. Lighting quick diagnostic scan, under 30 seconds on test vehicle (2012 VW Passat TDI). The large 13.1" screen is very easy to read, no more squinting to read live data. Battery life is very long, have not charged it yet after several hours of use. The customizable reports are well formatted and look professional, easily able to share to your Google Drive or any other Bluetooth receiver. Would have liked if it had included the assortment of adapters for OBD 1 makes and a normal sized Bluetooth VCI along with the SmartLink VCI. It's a bit much having to connect the SmartLink to the DLC just to perform a vehicle scan, I'll have to inquire about whether it can support 2 VCI's and the OBD 1 adapters I have from my previous Launch tool.You will still need to set up a dedicated PC for use with the vehicle manufacturers software and use the SmartLink C as the J2534 pass through, since it only has BMW and Mercedes-Benz PCM files in the cloud storage. Have not set up an FCA AutoAuth yet, may edit this review afterwards depending on the outcome. Pretty sure you are still required to pay the annual$50 AutoAuth subscription fee regardless. Very happy with the tool so far. It's heavy, rugged, and fast. Perfect for my shop environment.Dustman Diagnostics

For the price, it did exactly what I needed it to do. I accidentally removed the wrong fuse causing my air bag light on my dash to come on. This reset the fault code and saved me $$$ not having to go to the dealer. This will also allow me to reset the maintenance warning when I change my own oil.
